SIPHON FOR WATER-CLOSET TANKS.

Specification of Letters Patent.

Patented Nov. 17, 1908 Application filed February 4, 1907, Serial No.355,608. Renewed October 9, 1908. Serial No. 456,947.

To all whom it may concern:

Be it known that I, WILLARD F. RICHARD- SON, a citizen of the UnitedStates, residing in the city and county of Kalamazoo, State of Michigan,have invented certain new and useful Improvements in Siphons for WVater-Closet Tanks, of which the following is a specification.

This invention relates to improvements in siphons for water-closettanks.

The object of this invention is to provide an improved water-closet tanksiphon which is very economical to produce and at the same time onewhich is desirable and durable in construction with improved detachableguide for the valve lift rod or stem.

I accomplish the object of my invention by thedevices and meansdescribed in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure embodying the features of my invention is clearlyillustrated in the accompanying drawing, forming a part of thisspecification, in which,

Figure 1 is a perspective view of my improved Water closet tank siphon,a portion of the valve being broken away. Fig. 2 is a detail verticalsection through the valve seat. Fig. 3 is a detail section, taken on aline corresponding to line l-et of Fig. 1, the valve lift rod or stembeing removed from the guide therefor.

In the drawing, similar reference characters refer to similar partsthroughout the several views.

Referring to the drawing, my improved siphon consists of a body orgooseneck portion 1, havinga laterally projecting dis charge arm at itslower end, the discharge arm having preferably a threaded nipple 2adapted to receive a suitable coupling. Above the nipple 2 is anupwardly opening valve seat 3. The loop of the gooseneck is strengthenedby the brace 5. The end 6 of the siphon is cut on an incline to providea suitable vent as is usual in such structures. On the inside of thegooseneck is a projecting lug 7 having a rectangular vertical hole 8therethrough adapted to receive the downturned end 10 of the lift rodguide arm 9. The parts above described with the exception of the liftguide arm are all cast in one piece. The lift guide arm is provided witha vertical guide-hole 12 therethrough adapted to receive the lift rod orstem 13 of the valve 1st. The valve seats downwardly, as clearly appearsfrom the drawing. As the valve seat is cast integrally with the otherparts, and preferably of iron, I preferably provide a seat ring 15therefor. This seat ring is adapted to fit within the valve seat andforms, in reality, the seat proper, for the valve. The ring 15 isprovided with an outwardly projecting flange 16 at its upper edgeadapted to rest upon the top of the valve seat when the ring is insertedin position. This ring is suitably secured in position, which, onaccount of its shape is very easily accomplished.

The hole in the lug 7 for the lift rod guide arm is formed so that theguide arm is always held in the proper position. In the accompanyingdrawing, I illustrate the same as being rectangular in cross section,however, it is evident that it might be greatly varied as long as it isof irregular cross section to retain the arm positively in position. Bythus supporting the lift rod guide arm, I avoid the necessity for clampsfor securing the same, and, as stated, it is always held in properposition. Another very great advantage is that it can be removed andinserted by an inexperienced person, no care being required foradjusting the same.

My improved siphon is very economical in structure and very durable. Bycasting the parts in one piece, I avoid the necessity for joints, andconsequently expense and likelihood of imperfections.

I am well aware that detachable arms have been provided on these siphonswith vertical guide-holes for the stems of the ball valves or similarvalves which are adjustable and removable by means of set-screws and thelike. These require machining and screw-tapping and threading and theinsertion of screws. They are very likely to become displaced and arenot so effective as the simple castings which I have produced.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. In a structure of the class described, the combination with agooseneck or body portion having a laterally extending discharge arm atone end thereof, provided with a downwardly projecting threaded nippleand an upwardly opening valve seat; a lug having a vertical rectangularhole therethrough projecting laterally over said discharge arm, thesaidv parts being cast integrally; a valve; a lift rod therefor; and aguide arm for said rod having a downturned rectangular portion adaptedto be inserted in said opening in said lug, and a vertical guide-hole atits outer end adapted to receive said lift rod stem whereby said valveis supported and held in alinement with its seat and detachablyconnected to said body portion.

2. In a structure of the class described, the combination with the bodyor gooseneck having a laterally projecting integral lug thereon, saidlug having a vertical rectangular hole therethrough; avalve; alift rodor stem therefor; a guide arm therefor having a rectangular downturnedinner end adapted to be inserted in said hole in said lug, and avertical guide-hole at its outer end adapted to receive said lift rodwhereby said valve is detachably supported and held in alinement.

3. In a structure of the class described, the combination with the bodyor gooseneck having a laterally projecting lug with a vertical hole ofirregular cr0ss-section therethrough; a valve; a lift rod or stemtherefor; a guide arm for said lift rod or stem having a downturnedinner end conformed and adapted to be inserted through said hole and avertical guidehole in its outer end adapted to receive said rod asspecified.

In witness whereof, I have hereunto set my hand and seal in the presenceof two witnesses.
